Exegesis of the saying of Allah the Exalted: “O Children of Israel, remember My favor which I have bestowed upon you, and fulfill My covenant, I will fulfill your covenant, and fear none but Me,” and the grammatical analysis of “and fear none but Me”

In this noble verse, its apparent meaning is that they are eternal therein forever, and Allah has explicitly stated this in three known places.
Then he said: Who is Israel? He is Ya'qub (Jacob), the son of Ishaq (Isaac), the son of Ibrahīm (Abraham). So his grandfather is Ibrahīm, and Isma'il (Ismail)'s father is Ibrahīm, and his children are the maternal cousins of the Children of Israel. For this reason, the Arabs and the Children of Israel were maternal cousins, and fitnah, enmity, and hatred occurred between them. Consequently, the Children of Israel—meaning the Children of Muhammad (peace and blessings be upon him) were among them—envied the Arabs.
Remember it with your hearts, remember it with your tongues, and remember it with your actions. This is because gratitude encompasses these three things: the heart, the tongue, and the limbs.
And His saying: is a singular possessive noun, which encompasses all favors. Allah the Exalted bestowed many favors upon the Children of Israel, preferring them over all the worlds. Musa (Moses) (peace be upon him) said to them: .
And His saying: One might say: Does not His saying: suffice for it? We say: Yes, in terms of sufficiency it suffices, but mentioning it indicates the perfection of Allah's (Mighty and Majestic) favor, where He said: And with the verbal form indicating the creation of these favors, and that had it not been for Allah (Mighty and Majestic) being the One who bestowed them, they would not have been attained by them.
means: Bring it complete. And His covenant (Glorified and Exalted is He) is that He covenanted with them to establish prayer, give zakah, and believe in the messengers, as Allah the Exalted said: This is the covenant of Allah, What is the covenant of Allah with them? The One who covenanted with them, if they fulfill His covenant, that He will fulfill it: So if they had fulfilled the covenant of Allah, Allah would have fulfilled His covenant with them. There is a grammatical issue here. First, "arhabun" (fear) originally is "arhabuni" (fear me) with the yā' (I), and it is omitted for the sake of considering the rhyming endings. So if "arhabun" has taken its object, where is the operator for ? Whoever permits the operator to govern two objects has no issue, but whoever does not permit this, this is an issue. It is said that the operator in is estimated according to the context. And we can say: Fear Me, fear Me . As for the fā' in His saying: , it is said that it is for the beauty of the expression. And "rihba" (fear) is fear that implies an increase in being affected by what one fears, because you feel that it indicates softness and that this fear is an affecting fear.
